Description
Technical field
The utility model relate to sanitary pad, particularly a kind of work flow that daily life field uses short, be convenient for carrying, uptake is large, little, the antibacterial taste removal of volume, the convenient nursing pad containing acid fiber by polylactic that permeability is good.
Background technology
Nursing pad is a kind of have large capacity absorption, water holding capacity, and non-leakage, soft comfortable disposable sanitary articles, is widely used in the aspects such as child's nurse, paralytic's gatism, puerpera's nursing, gynecologic menstrual.Conventional nursing pad structure mainly forms by three layers, is arranged to be by top layer to the order of bottom: top layer, intermediate absorption sandwich layer and backing layer.Top layer material therefor normally bi-component synthetic fiber hot-wind nonwoven cloth, polypropylene thermal mangles or spun-bonded non-woven fabrics; Intermediate absorption sandwich layer adds the super resin that absorbs by Time of Fluff Slurry and forms; Backing layer is mainly PP breathable films.This shows, the top layer of routine care pad is by 100% petroleum-based synthetic fibers, do not there is bacteria resistance function, if do not used because having condition to change for a long time, baby easy diaper rash, the paralytic bedsore that is easy to get, thereby development and production to have the nursing pad of natural bacteriostatic function necessary.
Acid fiber by polylactic is to take cornstarch as raw material, and by fermentation, the series of processes such as condensation, polymerization, spinning makes, owing to containing lactic acid, surface is faintly acid, has good biocidal property and eliminates odor function, is applicable to very much making medical and health use material.
The structure of existing nursing pad causes its work flow longer, first first production top layer nonwoven and counterdie of nonwoven processing factory, and then by Sanitary Materials Factory, nonwoven, counterdie and wood pulp macromolecule are combined and formed, that is to say that a slice nursing pad finished product will just can complete through raw material plant and sanitary paper product assembling Liang Ge factory, tediously long production process has been wasted a large amount of human and material resources and financial resources.
Utility model content
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, provide a kind of work flow short, be convenient for carrying, uptake is large, the convenient nursing pad containing acid fiber by polylactic of little, the antibacterial taste removal of volume, good permeability.
For achieving the above object, the technical solution adopted in the utility model is: a kind of convenient nursing pad containing acid fiber by polylactic, by upper layer group zoarium and antiseepage bottom, formed, it is characterized in that, described upper layer group zoarium by from top to bottom order laying top layer, water conservancy diversion moisture absorption layer and absorbed layer form, these three layers are combined into one by hot melt; Described upper layer group is fit to be combined into one by PUR with antiseepage bottom;
Described top layer is 100% acid fiber by polylactic net; Water conservancy diversion moisture absorption layer is for refusing water type bicomponent fibers and the fibrous fibre web of super absorption; Absorbed layer is hydrophilic bicomponent fibers and the fibrous fibre web of super absorption.
As preferably, in water conservancy diversion moisture absorption layer, refusing water type bicomponent fibers, to occupy ratio be 90-95%; In absorbed layer, it is 50-60% that hydrophilic bicomponent fibers occupies ratio.
As preferably, the grammes per square metre on described top layer is 10-20g/m
2, the grammes per square metre of water conservancy diversion moisture absorption layer is 20-50g/m
2, the grammes per square metre of absorbed layer is 50-100g/m
2.
As preferably, the described water type of refusing bicomponent fibers is a kind of in HDPE/PP, PP/PET, and described hydrophilic bicomponent fibers is a kind of in HDPE/PP, HDPE/PET and PP/PET.
As preferably, described antiseepage bottom is overlay film nonwoven or refuses water nonwoven; As further preferably, described overlay film nonwoven is a kind of in spunbond, water thorn, hot-wind nonwoven cloth, and its grammes per square metre is 30-60g/m
2.
As preferably, the thickness of described upper layer group zoarium is 2-3.5mm.
The beneficial effect the utlity model has is as follows:
(1) by the method for once-forming, directly produced with the upper layer group of top layer, water conservancy diversion moisture absorption layer and absorbed layer fit, exempted routine care pad and first need to buy top layer nonwoven, guide layer and macromolecule absorber in nonwoven factory, then in hygienic material processing factory, top layer nonwoven, guide layer, macromolecule+wood pulp layer and counterdie have been combined with each other and are processed into the tediously long flow process that nursing pad carries out Compound Machining; Meanwhile, compound that upper layer group is fit compound with antiseepage bottom by PUR, after simple cutting, become finished product, the processing of nursing pad is directly completed in nonwoven production factory, greatly shortened work flow, reduced production cost.
(2) adopt high-absorption fiber to replace the granular macromolecule absorber using in routine care pad, can absorb the liquid of 100 times of own wts, and in production process, be difficult for dry linting, handled easily.Owing to surpassing, absorb the uniformity that fiber distributes in fibre web, make water conservancy diversion, diffusion and the absorption of liquid more even, be difficult for producing side leakage, the phenomenon of also having avoided pbz polymer core body in use easily to become to stick together, flock together simultaneously, thus hinder the absorption to liquid; Due to 1/2 of the nursing pad thickness that is pbz polymer absorber containing the super nursing pad thickness that absorbs fiber the same absorbent multiplying power in the situation that, greatly reduced the volume of product on the other hand, reduced shelf and take up room.
(3) adopt acid fiber by polylactic as skin-material, utilize the natural bacteriostatic of acid fiber by polylactic and faintly acid to control the possibility that infant diaper rash and long-term paralytic produce bedsore, simultaneously, acid fiber by polylactic surface is very smooth, even can not produce allergy to the most tender skin yet, thereby finally can obtain antibacterial taste removal, ventilative smooth, smooth surface, powerful good convenience type nursing pad, there is extraordinary popularization and prospect of the application.
